<li>启动我的SpringBoot应用，使用Postman来访问上传接口进行文件上传，上传接口地址：<a target="_blank" rel="noopener" href="http://localhost:8080/minio/upload">http://localhost:8080/minio/upload</a></li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_14-e830a29e.png"></p>
<ul>
<li>上传完成后，我们打开MinIO的管理界面可以看到上传后的图片，也可以通过返回的url来访问图片：</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_15-5b984441.png"></p>
<ul>
<li>我们可以调用删除接口来删除该图片，需要注意的是<code>objectName</code>值是存储桶中的图片相对路径，删除文件接口地址：<a target="_blank" rel="noopener" href="http://localhost:8080/minio/delete">http://localhost:8080/minio/delete</a></li>
</ul>

<p>经过上面操作，我们的SpringBoot应用已经可以完成文件上传与删除操作了，接下来我们结合Vue来实现前端上传图片到MinIO中，以<code>mall-admin-web</code>中的代码为例。</p>

<li>我们的SpringBoot应用需要支持跨域请求，否则Vue前端无法进行接口调用，我们先添加一个全局的跨域请求配置：</li>

<ul>
<li><p><code>mall-admin-web</code>的文件上传操作主要是在<code>singleUpload.vue</code>和<code>multiUpload.vue</code>中，下面我们以<code>singleUpload.vue</code>的修改为例。</p>
</li>
<li><p>我们需要把原来的OSS上传和现在的MinIO上传做个兼容操作，先在Vue实例的数据对象中添加三个属性：</p>
</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_17-166c1b2c.png"></p>
<ul>
<li>然后根据<code>useOss</code>属性设置<code>el-upload</code>上传组件的提交地址和提交参数：</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_18-0641a266.png"></p>
<ul>
<li>在<code>el-upload</code>上传文件之前的钩子函数中添加如下代码，对于使用MinIO上传的操作不进行获取OSS上传策略的操作；</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_19-e77bc4b1.png"></p>
<ul>
<li>最后在<code>el-upload</code>文件上传成功的钩子函数中添加如下代码，对于使用MinIO上传的操作直接从返回结果中获取文件url；</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_20-72ced895.png"></p>
<ul>
<li>运行<code>mall-admin-web</code>项目，使用商品分类下的添加功能来测试下文件上传，发现已经可以成功上传，图片也已经可以正常回显：</li>
</ul>
<p><img src="https://qiniu.ko25891wan.top/%E6%97%A5%E8%AE%B0%E8%BD%AF%E4%BB%B6/obsition/2024-02-02_22:53:14_minio_use_21-393d419b.png"></p>
